Gotta love it ....

New device boosts road time for Tesla, Leaf drivers
Date:
November 21, 2017

Vanderbilt University
Summary:
Nissan Leafs, which go about 107 miles on a charge, sometimes end up relegated to commuter cars due to battery-range worries. The mass-market, standard Tesla Model 3 can go double that but still can be disconcerting on long road trips. Both batteries could work up to 50 percent longer with a new device. It reconfigures modules -- clusters of battery cells -- in electric cars to be online or offline depending on whether they're going to pull down the other modules.

Pence's project management graduate class last year succeeded in building a working vehicle that uses magnets to levitate a few inches off an aluminum track. Batteries that ran down too quickly proved a major challenge.

When Potteiger returned from his fall 2016 NASA internship, he was eager to use what he'd learned in real-time prognostics: figuring out how much energy, say, a rocket or surface-roving device has left and how efficiently it's working. He heard some teaching assistants discussing Pence's levitation vehicle and started out volunteering to make a gauge for it.

Instead, the duo ended up with the battery switcher and are working with the Vanderbilt Center for Technology Transfer and Commercialization to get it to market.

I'd be interested to see what the second-hand market would be like for these first generation electric cars when better stuff comes along. Because with petrol cars, there's really not a massive difference between cars that came out 5 or even 10 years apart, but I wonder how someone's going to feel about buying a car with 70km range when all of the new ones can do 300+km.

Still, I'm glad that some people are taking the hit for the rest of us.

Hehe - yet Prius batteries for hybrids are being remanufactured as low as $600 and Perhaps EVs will see a similar boost as the article covers,.
It will depend on the volume sold. 70 km at the right price where fuel is high may still be viable- These EV batteries are good for 100,000 km just to get to 80% capacity ...tech like that mentioned might boost range and improve longevity

Early days yet.
